Cutting Big Holes In Thin Metal

[Rickabilly]

Here in the UK they are marketed as Q Max cutters and are available in 1mm size increments, as they are very hard they work in stainless but can chip from time to time which mucks up the finished edge but still priceless for installing panel guages, auto body lights and LPG filling points, I even have some square ones.

Oh and if you buy a thrust race either a ball style or needle roller style with a 10mm bore and use it under the nut that you are turning to close the punch into the die it reduces the torque required by a whole heap, well worth the investment.
